Installation-ready wall and stud cassettes

ABSTRACT

The invention relates to a wall casing ( 1 ) with a substantially flat configuration, with a front side ( 2 ) intended to face the space, and a rear side ( 3 ). The wall casing ( 1 ) comprises a carrier ( 10 ) and a casing core ( 20 ) and is intended to be mounted between a pair of studs ( 100 ). The carrier ( 10 ) has a recess ( 11 ), the opening ( 12 ) of which faces the front side ( 2 ) of the wall casing ( 1 ) and a backing ( 13 ). The width of the recess ( 11 ) is adapted to fit between two studs. The recess ( 11 ) is equipped with side walls ( 14   a,    14   b ) which are connected to flanges ( 15   a,    15   b ) on each long side ( 2   a,    2   b ).

TECHNICAL AREA

This invention relates to installation-ready wall and stud cassette that are assembled in a frame in order to achieve construction and financial advantages in the field of light construction technology.

TECHNICAL POSITION

When building new, or renovating existing, buildings and other structures today, light-building technology is often used. This means that various types of building boards are mounted on a framework of wood or steel with insulation in the cavity of the framework. Depending on the requirements stipulated for a construction, e.g. fire, noise, moisture, stability, electrical and piping, fasteners etc., the structure must be adapted with the appropriate framework, type of building boards, storage of building boards and insulation to achieve the correct values and function of the wall. This approach currently works, but there are shortcomings and there is potential for improvement.

Apart from wood, the attachment options of building boards and steel frames currently available on the market are relatively low, especially in the case of heavier installations with dynamic considerations. An extra layer of wood-based boards is often used on the outside of the framework to achieve the desired attachment. Alternatively, wooden nogging pieces or sheet metal are uniquely adapted for the respective fixing points on the framework before the building boards and surface layers are put in place, which makes it difficult to subsequently install heavier fastenings in the absence of nogging pieces. If you are forced to use multiple sheet layers, closer, deeper or double frameworks to comply with requirements and function, the economics and technology become unfavourable for several reasons:

-   -   Material and labour costs increase.     -   Using wood in humid environments poses a risk of rotting,         moisture and mould damages.     -   When a wall structure increases in size, usable floor space and         volume is lost and cannot be sold, rented or otherwise used in         the room/building.     -   In the case of new constructions, it is necessary to build         larger buildings to generate a certain amount of predetermined         usable square meters or volume in a building.

Solving this Problem

This invention of installation-ready wall and frame cassette decreases, and in some cases completely eliminates, the problems associated with current technology by providing the specifications stated in this patent application and patent claim.

DESCRIPTION OF THE INVENTION

The casings are characterized by the fact that they are ready for installation and installed on one or more sides of a wall system (200), instead of using multiple layers of building boards (500) on the outside of a wall system (200) to meet stipulated requirements (see example diagram 5). This saves material and assembly time, and thinner walls (300) can be constructed, thus freeing up usable space and volume in the room. The casings can handle relatively heavy attachments in comparison to the current technology with inorganic solutions, which is desirable in, for example, humid environments. Its flat design means the casings can utilize a portion of the frame depth (103) without competing with the insulation, pipes or electrical wires within the structure.

The casings are of a sandwich-like design and consist of a stabilizing but permeable core (20) of one or more materials in one or more layers of organic or inorganic material (e.g. building boards/hangings of plaster, cement, wood, glass, plastic, rubber, bitumen, etc.) in order to achieve durable function in varying installation environments (e.g. humid or non-humid environments), with fire and sound inhibitory properties. The core is equipped with a carrier (10) and/or backing (13) and, if necessary, a front side (2) of metal or equivalent material to generate strong and stable constructions and attachment options.

The wall casing (1) may be designed so that the flanges (15 a, 15 b) of the carrier (10) do not extend along the entire long sides (2 b, 2 b) of the entire wall casing (1 a). The flanges (15 a, 15 b) may be adapted so as to be removed from one or both of the short sides (3 a, 3 b) of the wall casings (1). This allows the wall casing to be fitted with the end down or end up between a pair of frames (100) connected to a rail (600) or similar along the upward and/or downward. If the flanges (15 a, 15 b) cannot be adjusted in this manner, the wall casing (1) will not be able to fit between the frames (100) and be pushed down into the rail. Thus, the length of the part from which the flanges are removed from its end must be at least equal to the height of the rail (600). Of course, it is also possible to remove the side walls (14 a, 14 b) of the carrier (10) and/or the backing (13) at the ends, if required.

The wall casing (1) may be part of a wall system (200) for the construction of walls (300). In addition to the wall casing (1), the wall system (200) may include a non-solid frame (100), such as a steel frame with a U or C profile equipped with a frame core (120) inside the frame side (101), to which the flanges (15 a, 15 b) of the wall casing are intended to be fastened. This means that the part of the wall (300) where the studs (100) are located will also be equipped with a core (120) so that there are no defective audio and fire prevention properties where the studs are located. An additional advantage of equipping the studs (100) with a stud core (120) is that they will improve the properties for secure attachment to the wall (300) behind which the studs (100) are located. The attachment properties can be further improved if the stud core (120) is equipped with a backing (13), consisting, for example, of the same material used for the carrier (10) in the wall casing, preferably made of a thin sheet and forming a stud casing (6). There may thus be a desire to use studs (100) equipped with a stud core (120), and possibly even with a backing (13), even when wall casings (1) are not used to construct the walls (300) between the studs (100). 

1. Wall casing (1) for inner walls and wall systems (200), where the wall casing has a substantially flat configuration and is intended, upon mounting, to have a front surface (2) consisting of a first surface intended to face the space to be bordered and a rear surface (3) consisting of a second surface intended to face away from the space to be bordered. The wall casing (1) is intended to be mounted between a pair of studs (100) and, when mounted, will have a width extending in a direction perpendicular to the studs and a longitudinal direction extending longitudinally on the studs.
